AUTOMATIC GATE.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed December 21, 1905. Serial No. 292,797.

To all whom it may concern:

Be it known that I, J osnrn L. hlANLOVE, a citizen of the United States,residing at Milton, in the county of Wayne and State of Indiana, haveinvented certain new and useful Improvements in Automatic Gates, ofwhich the following is a specification.

My invention relates to swinging gates which. may be opened and closedeither by trip-rods, that are moved by trips placed to be engaged by thewheel of a vehicle, or by hand-pulls located at a suit-- able distancefrom the gate; and my invention consists in the construction of thegatesupporting devices and catches used in connection therewith. as willbe hereinafter set forth.

In the accompanying drawings, Figure l is a perspective view of the'gate and its fittings. Fig. 2 is a detail plan view showing the fittingsattached to the gatesupporting post and to the gate, the parts beingpositioned as when the gate is closed. Fig. 3 is a similar view showingthe gate moved off of its vertical and horizontal center prior to thecommencement of its opening or closing movement. Fig. 4 is a sideelevation of the elbow that connects the upper horizontal bar of thegate to the front vertical bar, such elbow having a projecting lug orlatch. Fig. 5 is a detail view of a hand-operated gate-opening devicethat may be used in connection with the wheel-actuated trips orindependent thereof. Fig. 6 is a front view of a part of thecatch-supporting post, show ing a catch and a stop attached thereto, thelugs or latches that project from the gate or its elbows being shown insection; and Fig. 7 is a detail view of one of the catches that areattached to the back post for holding the gate open.

A gate supported by the fittings shown may be opened by the trips whichare placed to be moved by the wheel of a vehicle as it approaches thegate, the other trip that is subsequently engaged by the wheel closingthe gate after the vehicle has passed the gateway. The gate may also beprovided with hand-pulls for opening and closing the gate, for it isonly necessary to turn the gatesupporting bar that operates to firstraise the gate to release it from its retainingcatches, the bar andfittings throwing the gate off of its vertical center, so that it willswing either open or shut.

The gate-frame A is preferably made up of horizontal and vertical tubes,which are connected by elbows a, b, c, and d, the elbows c and (1 havingprojecting lugs or rigid latches l c and d, that engage catches attachedto the l posts B and B. The main gate-post C carries brackets e and f,such brackets having through the horizontal projecting portion thatclass of circular openings through which the bar D is passed. The upperend of the bar D above the bracket 6 is key-ended or squared and hasfast upon its squared portion an arm or link g, and to the lower end ofthe bar D below the bracket f there is attached a plate or double-crankarm 71, to which the trip-rods are attached. The vertically-supportedbar D above the lower bracket f has fast thereon yoke-bearings 'i i, thevertical members of the yoke-bearings being maintained to be disposed atright angles to the link or arm g, and the plate or double-crank arm his secured to the bar to be held at an angle of forty-five degrees withrespect to both the arm or link g and the vertical members of theyoke-bearing. The angular relation of the fittings g, h, and 71 upon thebar D, to which a turning movement isgiven to open or shut the gate,materially simplifies the construction'and does away with movable partson the turning-bar. j Thelower end of the elbow a bears upon the outerend of the arm or link 9 about the circular opening therethrough, andthe rear bar or tube of the gate-frame is passed through the opening insuch arm or link, so j that the weight of the gate will practically becarried by the arm, and to the lower portion of the bar or tube there isattached a yoke or forked plate 7c, providedwith a central recess 7c ofthe same circumference as the bar D, against which the recessed part ofthe yoke bears, and on each side of the central recess are smallerrecesses 7c, in which lie the vertical members of the yoke-bearing whenthe gate is either open or shut. The yoke or forked plate has projectingside members with parallel inner faces that are spaced about the samedistance apart as the outer j faces of the vertical members of theyokebearings. This construction admits of the gate being opened by hand,while the bar D is held against a turning movement. Thus in opening thegate by hand it is only necessary to lift its front end, when it may beopened, the gate when released closing automatically. l

The trips n n and the trip-rods m and 'm.

are arranged in the usual manner, so that the gate will be opened andclosed by a vehicle, and when the gate, as shown by Fig. 1, has the rodor bar D extended upward and is provided with arms 4) v and cross-bars ww, to which suitably-guided flexible connections are attached, as shownby Fig. 5, the gate may be opened by drawing downward upon hand-pullsattached to the ends of the cords or flexibleconnections, and it will benoted that the trips and the hand-pulls may be used together upon thesame gate or they may be applied independently.

The back or stop post B, against which the gate strikes when opened,carries two similarly-constructed catches 0 0, which are fastened to theface of the post that is farthest from the gate-post C. The catches 0each have horizontal projecting portions and coils 0, the ends of thecoils extending in ward and upward to provide inclined and resilientmembers, against which the lugs c.

and d of the elbows c and (Z abut when. the gate is swung open, and. inuse the lugs will ride upon the resilient and inclined ends of thecatches and after passing the ends will drop upon the horizontal partsto lie between the post and the coils, holding the gate open until thefront end is lifted above the catches, when the gate will swing acrossthe roadway.

The post B in line with the lug or latch of the elbow d has attached tothe side that is nearest to the post C a plate p, such plate having aprojecting portion with inclined sides, upon which the lug d may ridebefore resting upon the flat central part of the plate, A part of theoutward-projecting port-ion of the plate 12 is cut away to admit of theswinging of a stop-pin 1", that is pivoted to a vertical portion of theplate 29, and the pin may swing until arrested by one of the shouldersat the end of the recess. The end of the pivoted stop-pin 1 when againstone of the shoulders will be vertical and when against the othershoulder it is inclined. When the gate is swung from an open to aclosed. position, the lug or latch d on the lower front corner of thegate will ride upon the inclined part of the plate, and its movementwill be arrested over the horizontal portion of the plate by the pin,and when the gate is opened by hand in an opposite direction from whichit is opened by the trips or the hand-pulls the stop-pin will beinclined, so that the gate may be readily lifted over the pin whenraised by the opening and closing mechanlsm.

The catch 1: on the upper portion of the post B is placed to be engagedby the lug or latch 13 of the elbow c, and this catch is made from asingle piece of wire, a part thereof be ing shaped to lie against theface of the post,

to which it is secured by staples. This wire is bent upon itself toprovide a pair of vertically-disposed coils, from which extendoutward-projecting members, the ends of which are bent upward, such endsterminating so as to provide a space between them that is slightly widerthan the lug c. When the gate is closed, the lug or latch c ispositioned below the inclined. ends and between the coils of the catch0, the inner sides of the coils restraining swinging movement of theate.

6 When the vertically-maintained bar D is given a partial rotation inits brackets, the link 9 and the yoke-bearings by engagement with theyoke places the gate out of vertical alinement or off of its center, thefront end of the gate being lifted to release the lug or latch from thecatch, so that the gate will swing open and against the stop-post and inengagement with the catches thereon. A reverse action of the bar will.close the gate.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In combination with a swinging gate having a fixed stud that projectsfrom the gate, means for lifting and inclining the gate, of a catchattached to one of the posts to be engaged. by the stud such catchhaving a vertically-disposed coil and a part connected to and extendingabove the coil, for the purpose set forth.

2. In a swinging gate the combination with gate-operating means and afixed. stud attached to the front bar of the gate, of a catch attachedto one of the gate-posts the catch having vertically-disposed coils andupward-inclined members which terminate above the coils, substantiallyas shown.

3. The combination with a swinging gate, means for operating the sameand a projecting lug or latch which is fixedly attached to the gate, ofa catch having a coil or resilient portion and beyond the coil orresilient part an inclined projecting part over which the latch willride and then drop to be in line with the coil, substantially as setforth.

4. In combination with a swinging gate, means for operating the same toraise and incline the gate, and a fixed lug carried by the front bar ofthe gate, of a catch attached to one of the gate-posts such catch havinga projecting portion and a vertically-disposed coil, an inclinedterminal above the coil with which the lug is adapted to engage and thenpass beyond such part to drop in line with the coil, substantially asset forth.
